Thisinvention relates to locomotive tenders particularly constructed toreceive a novel form of fuel pusher means for moving the fuel forwardlyin the tender bin from the rear to the front thereof, placing 4it withinconvenient reach of the reman for delivering it to the locomotiveflrebox.

`In apparatus o f this type it has been customary toplace the operatingmechanism for the fuel pusher in the fuel bin at its upper rearward end.One of the objects of this inventionV is to provide a novel tender andfuel pusher construction in which the pusher operating mechanism may bemade more accessible and occupy nov space in the fuel bin.AV Y

4It is afurther object of the invention to provide` a novel fuel pusherand operating mechanism therefor that is simple in construction, compactin design and arrangement and efficient in operation.,

Other objects and advantages of the invention will become apparent fromthe following description when read iin connection with theaccompanying, drawings, in Vwhich 1 is a central, longitudinal verticalsection of the forward portion of a locomotive tender with the inventionapplied thereto;

Fig. 2 is a sectional View taken on the line 2--2 of Fig. 1; l

Fig. 3 is a centraLlongitudinal vertical section of the forward portionof a locomotive tender with an alternative form of the invention appliedthereto; and

Fig. 4 is a sectional View taken on the line 4-4 of Fig. 3.

On the drawings, referring more particularly to the preferred form ofthe invention illustrated in Figures l and 2, a locomotive tender isindicated generally at I0, comprising the fuel bin II and the watercompartment I2, the two being separated' by 'the rear slope sheet I3,side slope sheets I4 and I5 and the fuel bin bottom Wall or floor I6.A Acoal pusher, generally indicated by the numeral I1, is mounted in thefuel bin II and arranged to reciprocate longitudinally over the surfaceof the rear slope sheet I3 and the fuel bin floor I 6.V The coal pusherI'I comprises a .plurality of pusher heads, shown as four in number, andindicated respectively by the numerals I8, I9, 20, and 2l. The pusherheads 20 and 2I which reciprocate over the surface of the fuel bin oorI6 are in tandem arrangement and rigidly connected together by thelongitudinally extending tieplates 22 and 23. The pusher heads I8 and I9which reciprocate over the surface of the rear (o1. 10a-2.3m

slope sheet I3 are flexibly connected together by a plurailty of links24 and similarly connected with the rigidly attached pusher heads 20 and2 I.

The pusher heads are provided with an abrupt forward'face 25 to carryfuel with them on their forward movement and a sloping back 26permitting them to pass freely under the mass of fuel on their backwardmovement.

The rear slope sheet I3 is provided with a track 2'I along which thepusher heads I8 and I3 reciprocate. Y Along the intersection of the sideslope sheets I4 and I5 and the bin floor I6 there are secured in placein a suitable manner guide bars 28 and 29 forming with the floor I6guideways 30 and 3l respectively. The tie plates 22 and 23 are providedwith the laterally extending flanges 32 and 33 respectively, arranged tobe received in the guideways 3l! and 3| respectively, permittinglongitudinal sliding movement of the pusher heads 20 and 2|, butpreventing lateral and vertical movement.

The coal pusher I'I is operated by a reciproeating motor 34 which isrigidly secured tothe underside of thefloor I3 within the water tightvcompartment 35. The compartment 35 is formed by the upright Walls 36,3l and 38 together with the tender frame 39 and oor I6 and is open atits forward end. The piston rod 40 is reciprocated longitudinally withinthe compartment 35 and beneath the floor I6 by the motor 34. At itsforward end, the piston rod 40 is provided with a transversely extendingarm 4I, which is rigidly secured thereto and reciprocates therewith. y

The tie plates 22 and 23 are provided with the depending flanges 42 and43 respectively, which project through the longitudinal slots 44V and 45respectively in the floor I6 of the fuel bin II and are secured in asuitable manner as by bolts 46 and 41 to the opposite ends respectivelyof the arm 4I.

It is apparent therefore, that not only is there provided an unusuallycompact arrangement, but also the driving mechanism is convenientlylocated for purposes of inspection and repair and takes up no room inthe fuel bin.

In Figures 3 and 4 there is shown an alternative construction in whichthe lower end of the rear fastened with the pusher heads I8 and I9 inthe same manner as in the preferred form of the device. A motor 5l foroperating the pusher is mounted in the water tight compartment 52, whichis formed by the upright walls 53, 54, and 55 together with the floor I6and tender frame 39. The motor 5I is shown mounted on the frame 39 butobviously could be mounted from the underside of the floor IG as in thepreferred form of the device.

A bracket 56 is securely fastened to the upright wall 53 in thecompartment 52 and a lever 51 is pivotally mounted intermediate its endsfrom the bracket 56. A pitman 58 connects one end of the lever 51 withthe pusher member 50 and a pitman 59 connects the other end of the lever51 with the motor 5I.

In this form of the device, a somewhat larger compartment is necessaryto house the driving mechanism than in the preferred form of the devicebut the advantages in other respects are the same.
